Methyl (triphenylphosphoranylidene)acetate Chemical Properties,Usage,Production

  • Chemical Properties white to off-white powder
  • Uses
    1. (Methoxycarbonylmethylene)triphenylphosphorane is used in olefination reactions. Wittig reagent for the two-carbon homologation of aldehydes to α,β-unsaturated esters. it undergoes the Wittig reaction with aldehydes to give substituted methyl acrylates.
    2. used in an efficient synthesis of pyrazoles via reaction with methyl diazoacetate in the presence of triethylamine.
    3. It is used in the preparation of (triphenylphosphoranylidene)-ketene.
    4. The Wittig reaction we performed in class involved the reaction of 2-nitrobenzaldehyde (1) with methyl (triphenylphosphoranylidene) acetate (2) to produce methyl (2E)-3-(2-nitrophenyl) acrylate (3) with a triphenylphosphine oxide (4) side product, and took place in a silica gel matrix to ensure even product dispersion for chromatography.
      Wittig Reaction
  • Purification Methods Crystallise it by dissolving in it AcOH and adding pet ether (b 40-50o) to give colourless plates. UV max (A 1mm ): 222nm (865) and 268nm (116) [Isler et al. Helv Chim Acta 40 1242 1957]. [Beilstein 16 IV 977.]
